FIELD: physics.
SUBSTANCE: invention relates to a device for vacuum degassing of molten glass mass. The device for vacuum degassing of molten glass mass comprises a crucible and a vacuum bell jar. The crucible is mounted on a pusher rod with a movable hearth. A cushion of granular material is sprinkled on the floor. The device has an extensible cover, under which the vacuum bell jar is mounted with possibility of contact with the cushion of the movable hearth when the extensible cover is open.
EFFECT: vacuum degassing device which improves the quality of molten glass mass.
